Required reporting of gunshot and other wounds

(a) Any medical provider who provides medical treatment to a person suffering from a wound caused by a gunshot or a knife or other sharp or pointed instrument, under circumstances which would lead a reasonable person to believe resulted from a violation of the criminal laws of this state, shall report the same to a law-enforcement agency located within the county within which such wound is treated. The report shall be made initially by telephone and shall be followed by a written report delivered to such agency within forty-eight hours following the initial report: Provided, That where two or more persons participate in the medical treatment of such wound, the obligation to report imposed by this section shall apply only to the attending physician or, if none, to the person primarily responsible for providing the medical treatment. (b) Any medical provider person who in good faith reports a wound described in subsection (a) of this section shall be immune from any civil liability which may otherwise result solely from reporting the same.
